A twin-turbo setup makes it almost as powerful as a V8.
The Hurricane twin-turbo engine makes its complete and official debut less than 24 hours after Jeep’s online configurator disclosed early data about the brand’s new inline-six-cylinder gasoline engine. The new 3.0-liter straight-six engine, which is designed to equal the output of the larger V8 engines, is up to 15% more efficient than an eight-cylinder engine, and Jeep will sell it in two power stages, depending on the application.
Let’s get right down to business. The new 3.0 twin-turbo engine produces “greater than” 400 horsepower (294 kilowatts) and 450 pound-feet (610 Newton-meters) of torque in its basic configuration. This version uses cooled exhaust gas circulation and is tailored for the optimum fuel economy. The High Output model, on the other hand, boasts “greater than” 500 horsepower (368 kW) and 575 lb-ft (780 Nm of torque, as well as the promise of “considerable” fuel economy when towing.

I A deep-skirt cast-aluminum block with a structural aluminium alloy oil pan serves as the foundation for the new 3.0 I6.

A dedicated chain-driven shaft actuates a high-pressure direct fuel injection system with a single pump for the standard version and two pumps for the more powerful version. Both variants are equipped with a start-stop mechanism that reduces emissions when used in cities.

As a result of the hardware solutions, Jeep says the new engine delivers a flat torque curve with the engine maintaining at least 90 percent of its peak torque from 2,350 rpm all the way to its red line. The architecture of the inline-six unit makes it suitable for future integration of electric support, which means a hybrid Hurricane engine could deliver even more power and less harmful emissions.
Jeep explains the exact output numbers will vary depending on the application with the first vehicles powered by the Hurricane engine expected to reach dealerships later this year. The Grand Wagoneer is going to be among the first to receive it and there have been rumors about the next-generation Dodge Challenger and Charger also getting it as a more efficient and eco-friendly alternative to today’s V8.
